Many, many things to do as you travel along Route 2 in Vermont.
Start by camping at
North Beach in Burlington, close enough to this great little city that you can bike to a really vibrant downtown for shopping, dinner or entertainment.
If you must, there is the Ben and Jerry's factory on Route 100 just north of Route 2 in Waterbury Center. Personally, I'd just stop anywhere and buy their ice cream to eat as I traveled along.
As Mistermike said, don't miss the smallest state capital city in the country. Just walk right in under the golden dome, the doors are usually wide open.
Take a short side trip to Barre, VT for a tour of the
Rock of Ages Granite Quarry and a walk around the
Hope Cemetery.
Do not miss
Rainbow Sweets in Marshfield, Route 2 northeast of Montpelier. Run and hosted by an acerbic New York transplant, you will never be disappointed with his offerings for lunch, dinner and certainly not for dessert.
Another slight detour up Hwy 215 from Marshfield will bring you to the
Cabot Cheese factory in Cabot, VT. Current price for a
tour is $2 and children under 12 are free and they give sample too!
For a truly unique and nostalgic experience, visit
The Fairbanks Museum and Planetarium in St. Johnsbury as you near the New Hampshire border.
And all along your way you'll enjoy the burst of flowers and green that spring brings to the north country.
(Oh yes, I think I'd estimate a bit more than 8 hours from Burlington to Bangor.)
